SM Series Vernier Micrometer Head

Product Description

• The vernier micrometer is a standard actuator for the manual drives of most translation stages;
• Standard Ø9.5 mm mounting shank with a knurled adjustment knob for easy gripping;
• Pitch of 0.5mm (50.8TPI), direct reading in 10μm increments with a vernier reading of 1μm;
• Equipped with a 4mm hexagonal recess for adjustment even in confined spaces.

The vernier micrometer serves as a standard actuator for the manual drives of most translation stages. The SM25 features a 25mm travel range and a load capacity of 23lb, while the SM13 has a 13mm travel range and a load capacity of 9lb. The micrometer has a pitch of 0.5mm (50.8TPI), with direct reading in 10μm increments and a vernier reading of 1μm.

Technical Description

(1) The spindle end features single-point contact, and the ribbed friction sleeve maintains a constant force for finer adjustment and positioning. This effectively avoids errors caused by excessive force and reduces positioning alignment errors.

(2) The SM25 micrometer head has a travel range of 25mm, and the SM13 micrometer head has a travel range of 13mm. The vernier scale is 1mm; the pitch is 0.5mm, with direct reading in 10μm increments and a vernier reading of 1μm. The laser-engraved scale is clear, wear-resistant, fade-proof, low in error and enables more accurate measurement.

(3) The micrometer knob is designed with a hexagonal recess, which allows adjustment with a 4mm hexagonal wrench even in confined spaces. It is adaptable to various installation scenarios and offers higher compatibility.
